Use the properties of operations and rules for multiplying and dividing to solve(−2)×(15)÷(23)×(−56)÷(34) Fractions
−2/3
2/3
1/6
−1/6
To solve this expression, we need to first simplify the multiplication and then perform the division. Let's start by multiplying the numbers:
(-2) × (15) × (-56) = 1680
Now we can rewrite the expression as:
1680 ÷ (23) ÷ (34)
To divide by a fraction, we can multiply by its reciprocal:
1680 ÷ (23/1) × (1/34) = 1680 × (1/23) × (1/34)
When multiplying fractions, we multiply the numerators together and the denominators together:
1680 × 1 × 1 = 1680
-----
23 × 34
So, the simplified expression is:
1680 ÷ (23 × 34) = 1680 ÷ 782
Now, we can perform the division:
1680 ÷ 782 ≈ 2.151
Since the question states "Fractions" at the end, it seems like there may have been a typo in the original question. If the expression is supposed to be solved as fractions, the answer would be:
2/150 ≈ 1/6
So, the correct answer is 1/6.
To solve the expression (-2) × (15) ÷ (23) × (-56) ÷ (34), we need to follow the properties of operations and rules for multiplying and dividing.
First, let's calculate the numerator:
(-2) × (15) × (-56) = 1680
Next, let's calculate the denominator:
(23) × (34) = 782
Then, divide the numerator by the denominator:
1680 ÷ 782 = 2.15 (rounded to two decimal places)
Therefore, the solution is 2/3.
To solve the expression (-2)×(15)÷(23)×(-56)÷(34) involving fractions, we need to follow the order of operations, which dictates that we perform the multiplication and division operations from left to right before performing any additions or subtractions.
First, let's calculate the multiplication: (-2) × (15) × (-56) = 1680.
Next, let's calculate the division: 1680 ÷ 23 ÷ 34. To divide a number by a fraction, we can multiply by the reciprocal of the fraction. Hence, we have (1680 ÷ 23) × (1 ÷ 34).
Now, let's calculate the division of 1680 by 23: 1680 ÷ 23 = 73.04348 (approximately).
Lastly, let's multiply the result by 1/34: 73.04348 × (1 ÷ 34) = 2.147826 (approximately).
So, the final answer is 2.147826.
